I booted the RPi2B v1.1 that I have access to, using
(long output line split for readability):

# uname -apKU
FreeBSD OPiP2E_RPI2v1p1 14.0-CURRENT FreeBSD 14.0-CURRENT #49
main-n258610-ba7319e9091b-dirty: Fri Oct 14 18:27:46 PDT 2022
root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA7-nodbg-clang/usr/main-src/arm.armv7/sys/GENERIC-NODBG-CA7
arm armv7 1400072 1400072

(It also has a armv7 EFI loader from the closest artifact
build before the change that broke armv7 for that. I've
not yet updated to recent enough to have your fix.)

My updates track /etc/ changes via etcupdate in the scripts
I use (etcupdate since git). I do not get any of the lines:

Soft Float compatibility ldconfig path:
ldconfig: illegal option -- o
usage: ldconfig [-32] [-elf] [-Rimrv] [-f hints_file] [directory | file ...]


I'll note that the man arch lists "soft" in some
places in the Floating Point table, just not for
armv7. Showing the ones that do list "soft":

   Floating Point
           Architecture    float, double    long double
           aarch64         hard             soft, quad precision
. . .
           mips            soft             identical to double
           mipsel          soft             identical to double
. . .
           mipsn32         soft             identical to double
           mips64          soft             identical to double
           mips64el        soft             identical to double
. . .
           riscv64sf       soft             soft, quad precision

aarch64 and riscv64sf would apply to main [so: 14] for
long double. But I'm unsure of any implications for "Soft
Float compatibility ldconfig path".

run_rc_command "$1"

By contrast, https://cgit.freebsd.org/src/tree/libexec/rc/rc.d/ldconfig?h=releng/12.4
still has the code:

		case `sysctl -n hw.machine_arch` in
		armv[67])
			for i in ${ldconfig_localsoft_dirs}; do
				if [ -d "${i}" ]; then
					_files=`find ${i} -type f`
					if [ -n "${_files}" ]; then
						ldconfigsoft_paths="${ldconfigsoft_paths} `cat ${_files} | sort -u`"
					fi
				fi
			done
			_LDC=""
			for i in ${ldconfigsoft_paths}; do
				if [ -r "${i}" ]; then
					_LDC="${_LDC} ${i}"
				fi
			done
			check_startmsgs &&
			    echo 'Soft Float compatibility ldconfig path:' ${_LDC}
			${ldconfig} -soft ${_ins} ${_LDC}
			;;
		esac

As does https://cgit.freebsd.org/src/tree/libexec/rc/rc.d/ldconfig?h=releng/13.1 .
As does https://cgit.freebsd.org/src/tree/libexec/rc/rc.d/ldconfig?h=stable/13 .

So it looks like only main [so: 14] has that code removed.
